I-75 South Metro Express Lanes

Georgia, USA
-
One of the nation’s longest interstates, I-75 is also one of the most heavily congested. Faced with a large highway funding shortfall and a rapid increase in commuter travel, innovative approaches to ease congestion we sought.

reversible tolling system in Georgia

$13M

in estimated savings

More than 100,000 vehicles travel the 12-mile section of Interstate 75 (I-75) that connects Henry and Clayton counties each day. This region, located south of Atlanta, Georgia is an area of rapid population growth and development, and traffic often exceeded the capacity of the interstate, resulting in congestion, delays and safety issues. Arcadis addressed these challenges through the implementation of managed lanes.

The I-75S Metro Express Lanes project is the first reversible tollway in Georgia and only one of three in the Southeast. Arcadis’ design added two variable-rate toll lanes that alternate the direction of traffic flow to meet peak congestion demands. The new lanes were added using the existing median space, and access and exit points are limited.

Arcadis was able to identify more than $13 million in savings for this project, and our design and permitting expertise enabled the contractor to begin construction four months early. By facilitating coordination between our firm, the Georgia Department of Transportation, tolling integrators and the contractor, we overcame the implementation and technical challenges that arose throughout the project.

Arcadis has assisted agencies across the country with the design and implementation of managed lanes. Our multidisciplinary team of highway and bridge engineers and construction specialists have applied their experience on some the nation’s largest and most successful design-build projects.
